Occupational factors, particularly ergonomic ones, contribute to fetal deaths and preterm births in pregnant workers. Early withdrawal from exposure can prevent many adverse fetal outcomes, but poses employment equality challenges.

Area of Science:

  • Occupational Health
  • Reproductive Epidemiology
  • Public Health

Background:

  • Pregnancy involves unique risks for employed women.
  • Understanding occupational hazards is crucial for maternal and fetal well-being.
  • Previous research has indicated potential links between work and adverse pregnancy outcomes.

Purpose of the Study:

  • To quantify the risk of adverse fetal outcomes associated with specific occupational groups and work demands.
  • To estimate the number of fetal deaths and preterm births attributable to occupational factors.
  • To assess the potential impact of early withdrawal from occupational exposure on preventing these outcomes.

Main Methods:

  • Analysis of a large survey on work during pregnancy in Montreal (1982-1984).

  • Estimation of expected fetal deaths and preterm births among pregnant women in Quebec (1985).
  • Calculation of fetal deaths and preterm births attributable to occupational factors, focusing on ergonomic aspects.

    • Main Results:

    • Approximately 680 fetal deaths were linked to occupational factors, primarily ergonomic.
    • Around 110 preterm births were potentially related to occupation.
    • Early withdrawal from exposure (around 10 weeks) could prevent half of occupation-related fetal deaths; delaying until 16 weeks reduces this benefit significantly.

    Conclusions:

    • Occupational factors, especially ergonomic ones, pose a significant risk to fetal outcomes.
    • Timely intervention through reassignment or paid leave can substantially reduce fetal deaths and preterm births.
    • Implementing such interventions requires careful consideration of financial costs and potential impacts on women's employment equality.
